1 Claim.

This invention relates to an improved shoe, and one of its objects is toprovide a shoe with an upper which will expand to prevent excessivepressure on a foot which has swelled from exercise or any physiologicalcause.

Another object of the invention is to provide a shoe with an upper whichmay be detached by the wearer himself from the sole and heel, and adifferent upper connected thereto, without requiring special skill, sothat warmer or cooler upper-s may be used in winter or summer, as thewearer may desire.

With the above and other objects in view the invention comprises certainnew and useful constructions, combinations and arrangements of parts,clearly described in the following specification, and fully illustratedin the drawings, in'

which:

Fig. 1 is a perspective of a completed shoe.

Fig. 2 is an assembly view in perspective of three complementary partsfor binding the outturned edge of the upper to the marginal edge of thesole.

Fig. 3 is a transverse sectional view, taken on line 3-3 of Fig. 1,looking in the direction of the arrows.

Referring to the drawings, which illustrate the practical embodiment ofthe invention, 5 designates a shoe upper, which may be constructed ofany suitable material, leather, fabric, or composition material, andwhich is formed with an outturned marginal edge 6.

The marginal edge 6 is secured to the marginal edge 1 of the sole 8,which may be leather or any other material, by means of the clampingunit 9, which consists of a U-shaped forward section I ll, opposing sidesections II and I2, and a U- shaped rear section I3.

The forward section I0 is formed with an inner U-shaped jaw Ida and anouter U-shaped jaw Ifib, which is connected thereto by the hinge Iflc,which is equipped with a spring closing coil Iild, adapted to hold theinner jaw Iila in clamping relation to the outer jaw I012.

The side section I I is constructed with an inner or upper jaw Ila and alower or outer jaw IIb, connected to each other by the edge spring H0and the hinges Md. The side section I2 is constructed with a lower orouter jaw IZa and an upper jaw I211, which are connected to each otherby means of the hinge I20 and held toward each other by means of thecoil spring I 2d.

The U-shaped rear section I3 is constructed with an upper jaw I 3a whichis hinged to the lower or outer jaw I3b by means of the hinge I30, andengaged by the coil spring I301.

The inner section of each part of the clamping unit is adapted to swingupwardly, and the lower or outer section is secured to the marginal edgeof the sole 8 by means of the tacks I4.

The outer edge of the sole 8 is faced by an edging strip or loop I5, andthe upper leaf of each section of the clamping unit is faced by astripping I6. This stripping is constructed in sections corresponding tothe shape and size of the sections of the clamping unit, but providedwith adjacent overlapping ends. The section IEia is adapted to cover theforward unit section It, the section 161) is adapted to cover the unitsection II, the section I is adapted to cover the side unit section I2,and the section Kid is adapted to cover the unit section I3. Theadjacent ends of the sections overlap at I1, I8, I9 and 20, and arecoupled to each other by means of the button snaps 2|.

The marginal edge of the flexible upper 5 is held to the sole solely bythe clamping action of the unit 9, and when unusual pressure is appliedto the upper, the upper may expand by slipping its connection with thesole, thus avoiding extreme pressure on the foot, preventing thedevelopment of corns, and providing means for maintaining the shoe inthe most desirable service condition.

At various times of the year the feet have a tendency to expand orspread out, and 'because of a large variety of physiological causes feetwill swell. It is found that persons subject to expansion of their feetwill suffer keenly, and the present invention provides means forrelieving pressure on the feet to prevent pain and general discomfort.

By opening the upper leaves of the sections of the clamping unit theupper may be entirely detached, and a different upper connected with theshoe sole, the rear end of which is provided with the usual heel 8a,permanently connected to the sole.

It is understood that various changes in the details of construction,their combination and ar- ESTHER SUDIAH. ESTHER SUDIAH, Legalrepresentative for Rachel Sudiah, De-
